Answer:

$6.8

Step-by-step explanation:

Let x be the amount of money in Molly's amount

according to question,

4x-25=2.20

4x=2.20+25

4x=27.20

x=27.20/4

x=6.8

So,the amount of money in Molly's amont is $6.8

Answer: $6.80

Step-by-step explanation:

We will represent the amount of money that Molly has with a m. So it tells us the relationship between Kevin's amount and Molly's amount. It is says Kevin has 2.20 less that 4 times Molly's amount so we could represent it by the equation.

25 = 4m -2.20   solve for m.

+2.20     +2.20

27.20 = 4m

m= 6.8

4(6.8) = 27.20 - 25 = 2.20

2a. Determine the equation of the line connecting the points (0, -1) and (2, 3) *
Sauron [17]
First create the equation y=Mx+ B

B is the y intercept so when y = 0, B = -1.

Now we have y=Mx - 1

The slope is M. We can calculate this by using the formula M = (y2 -y1) / (x2 - x1)

Use the points (0, -1) and (2,3) for these values. So y2 = 3, y1 = -1, x2 = 2, x1 = 0

Plug them into the equation and solve

M = (3 + 1) / (2 - 0)
M = 4/2 = 2

Now we have the equation y = 2x - 1

Next to figure out if the points given are on the line you take the values and plug them into your equation like so: 4 = 2(-2) - 1

2(-2) - 1 does not equal 4 so this point does not fall on this line. Follow this same procedure for the next point given.

What is the value of the fourth term in a geometric sequence for which a1 = 30 and r = 1/2?
Pani-rosa [81]

Answer:  The required fourth term of the geometric sequence is \dfrac{10}{9}.

Step-by-step explanation:  We are given to find the value of the fourth term in a geometric sequence with first term and common ratio as follows :

a(1)=30,~~~~~r=\dfrac{1}{2}.

We know that

the n-th term of a geometric sequence with first term a1 and common ratio r given by

a(n)=a(1)r^{n-1}.

Therefore, the fourth term of the given geometric sequence will be

a(4)=a(1)r^{4-1}=30\times r^3=30\times\left(\dfrac{1}{3}\right)^3=\dfrac{30}{27}=\dfrac{10}{9}.

Thus, the required fourth term of the geometric sequence is \dfrac{10}{9}.

The diagonals of a square measure 14 cm. Which is the length of a side of the square? f.142√ cm g.72√ cm h.143√ cm j.73√ cm
Lera25 [3.4K]
Since it is a square, the diagonals are congruent. If a square is split like this, it becomes two congruent right triangles. The relationship between the sides and hypotenuse is a 1:\sqrt{2} ratio. So if the diagonal of a square is 14 cm, then the side length would be 14/\sqrt{2}, which is approximately 9.899. I don't understand what the answer choices are, but you should be able to square root the numbers to determine the answer.
